Along with gunshot wounds, others were trampled and hurt trying to climb over fences to get away.

Police and federal investigators still do not have a motive.

Islamic State is claiming responsibility, saying the gunman was one of its "soldiers" and converted to Islam months ago. The FBI says there is no evidence Paddock was tied to any international terror group.

Investigators say Paddock had a girlfriend, but believe she is in Tokyo and was not involved.

Paddock's brother, Eric, is just as baffled as police by his motive. He said the family is "horrified and bewildered."

He said his brother was a wealthy man with no known political or religious affiliations, no ties with white supremacists and no history of mental illness.

Eric Paddock also said their father was a bank robber who was at one time on the FBI's most wanted list. The FBI called him psychopathic and dangerous. But that the brothers had no contact with their father.

在发生了美国有史以来最血腥的单人枪击杀人事件的拉斯维加斯，人们排起要等候长达8个小时的长队，为枪击事件的受害者献血。

已被确认为64岁的史蒂芬·帕多克（Stephen Paddock）星期天晚上在有2万2000多人参加的乡村音乐会上肆意射击，警察向他逼近时自杀。

帕多克在室外音乐会场地对面的曼德勒湾酒店娱乐场32层的房间开枪，打死59人，打伤527人。
